Abstract (en)
An imaging unit takes a color image of a screen (a two-dimensional light-emitting region). An optical sensor outputs a signal indicating the color of a predetermined measurement point included in the screen. A first correction is a correction in which tristimulus values of the predetermined measurement point are used to correct tristimulus values of each of a plurality of measurement points included in the screen. A second correction is a correction in which a predetermined correction coefficient is used to correct the tristimulus values of each of the plurality of measurement points included in the screen. A correction unit executes the first correction when the screen is determined as being in a bright state and executes the second correction when the screen is determined as being in a dark state.
